Fixed Bed Absorbent Systems – Design Best Practice
Fixed bed absorbent technologies are commonly used for natural gas purification in a variety of applications. These can be regenerable or non-regenerable depending on the contaminant being removed and the specific duty. For non-regenerable absorbents such as PURASPECJMTM, H2S and Mercury removal are amongst the most frequently seen applications on a Gas Processing Plant. Whilst these technologies exhibit durability and robust performance in a range of operating conditions and fluid compositions, there are several operational issues which could impact on long term performance. This presentation will take a general look at troubleshooting common issues for fixed bed absorbents and address possible mitigation methods to consider during operation and at design stages to avoid problems in future.
